摘要

为研究N,+,注入对植物耐旱性的影响，实验以甘草为试材，以15%聚乙二醇（Polyethylene glycol，PEG）为渗透胁迫培养条件，研究不同能量的低能N,+,注入对甘草耐渗透胁迫的影响。结果表明，对甘草干种子注入总剂量为4.68×10,16,/cm,-2,，在15% PEG的渗透胁迫下，20keV的N,+,注入与对照相比，甘草株高生长增加40.2%(,p,<,0.01)，叶内多糖含量增加84.8% (,p,<,0.01)；在渗透胁迫下，株高生长和叶内多糖含量呈极显著正相关（,r,=0.7166，,p,<,0.01）。这一N,+,的注入参数可供提高甘草耐旱性种植,发挥当代刺激效应，对甘草进行离子束注入时参考。

Abstract

In order to study the effects of N,+, implantation on osmosis stress resistance of plant, the experiment was taken with liquorice as plant model and 15% PEG as the osmosis stress agent. The results showed that the stem height growth of liquorice increased by 40.2% compared with controls (,p,<,0.01 and internal polysaccharide in leaves increased by 84.8% (,p,<,0.01 after 20keV nitrogen ions implanted. The stem height growth showed evidently the positive correlation with the in internal polysaccharide in leaves under osmosis stress (,r,=0.7166,p,<,0.01) The selected N,+, implantation parameters may be useful to increase osmosis stress resistance cultivation of liquorice and to make it mutatedwith ions beam implanation.
